Infosys (INFY Quick QuoteINFY - Free Report) reached a significant support level, and could be a good pick for investors from a technical perspective. Recently, INFY broke through the 20-day moving average, which suggests a short-term bullish trend.

The 20-day simple moving average is a popular investing tool. Traders like this SMA because it offers a look back at a stock's price over a shorter period and helps smooth out price fluctuations. The 20-day can also show more trend reversal signals than longer-term moving averages.

Like other SMAs, if a stock's price is moving above the 20-day, the trend is considered positive. When the price falls below the moving average, it can signal a downward trend.
